Mach 5 Audio IXL-18.4 Build

I finally finished my IXL-18.4 HT subs. I went with 12 cubic feet tuned to 16 hz. Here are a few pics of the build.

Case contruction.


Bracing.



Foam lining installed.


Test fitting the triple ports. The sub magnet butts up against the center horizontal brace.


Final assembly.


Subs in place along the back wall of my HT.


Next is grill construction. I glued scraps from the build into a 24 inch square 1.5 inches thick. I cut the inside circle just a hair smaller then the diameter of the sub. I sanded it until it snuggly fit over the sub. The sub frame is 1 inch wide and the outside is rounded over with a 3/4 inch round over bit.


Test fit on the sub.


Painted the grill frame flat black. I had some stretchy grill cloth from a previous build.


Hot glued the fabric onto the grill frame and trimmed off the excess.


Final product.


Grills installed.


Painted the port screws flat black. All done!


Retired Shiva sonotubes.


I also have a pair of Ascendant Audio Atlas 15's. one on each side of the couch. They are 10 cubic feet tuned to 17hz.


From behind the couch looking forward. Now it's time to replace the RPTV with a projector. That will be my next project.


Replaced the RCA 480i RPTV with a Samsung 67 inch 1080p DLP LED TV December 2008. Merry Christmas to me!

I have always wondered what it would be like to have enough low end. I don't have to wonder anymore. These subs are awesome. The Atlas subs "strained" at loud passages on movies. With the IXL's now added to the pack, the bass is effortless! What a difference! I'm loving it!

Re: Mach 5 Audio IXL-18.4 Build

Yeah, they are big. And are they ever loud and low. I downloaded some frequency sweep tests and it's very obvious there are a couple of peaks. I"ll have to get some measurements done to see where the problems are.

Re: Mach 5 Audio IXL-18.4 Build

Very nice.

What are the specs on the elbow pieces you found to turn/extend the PSP ports? The local Lowes/HD don't seem to carry anything approaching the thin wall diameter of the PSP ports. I haven't gotten serious enough to hit up plumbing supply houses.

Thanks.

Nice subs! BTW, what are your plans for the Shiva Sonotubes? I might be interested in them. PM when you have a chance.

Re: Mach 5 Audio IXL-18.4 Build

Brent, the elbows are 4 inch PVC, schedule 40, thinwall. The openings were about 1/16 of an inch to big for the port tube. I "stabalized" the tube in the fitting by wrapping one wrap of electrical tape around the tube. I then used hot glue to glue them together, in case I need to "unglue" them in the future if I need to make any adjustments to the length.

James, The Shiva tubes are spoken for.

thxgoon, the piano is doing ok so far. But the emu eggs on top had to be moved! The last time I experimented with test tones I broke some of the wifes crystal glasses. No more "mistakes"!
